BMI and yet have very little body
fat. Conversely, an athletic individual may have a high
BMI and yet have little
body fat.

Any adult with a BMI of 25 or greater is considered overweight. For an adult, overweight is defined as a BMI of greater than or equal to 25, and obesity is defined as a BMI greater than or equal to 30.

What is considered Obese?

It’s calculated by dividing your weight in kilograms by the square of your height in meters (kg/m2). Because the BMI scale is not linear, it’s considered inaccurate in people who have a BMI of 30 or more.

a high BMI, you’re at risk for developing other illnesses like diabetes or
heart disease. It’s important to know where you’re at and how you can make your
BMI lower.

useful tool to measure and monitor changes in your weight over time.
